The ATM90 rounds out the ATM60 product family with hollow shaft variants. The ATM90 functions reliably even under harsh ambient conditions. Its rugged, mechanical design ensures maximum reliability and long service life. The magnetic singleturn scanning allows for a resolution of max. 13 bit within one revolution. The output or recording of the number of revolutions, max. 13 bit, is performed by a mechanical, almost wear-free gear. This means the ATM90 does not need a battery. Its short installation depth of 60 mm, combined with high shock and vibration resistance, makes the ATM90 perfect for use in applications with high mechanical loads and pronounced climatic fluctuations.
